REMINGTON.

l MPROVEMENT I N CEMENT COMPOUNDS.

To all whom it may concern:

Be it known that JOHN R. REMINGTON, deceased, late of the county ofMacon and State of Alabama, was the inventor of a certain I'mprovedCement, which he denominated Remingtons Ohemico-ltlechanical Cement; andI, WILLIAM H. POINDEXTE a, of Fayette County, Tennessee, administratordebom's 'non of the said deceased, do hereby declare that thefollowing'is a full and exact description thereof so far as the same hasbeen made known to me.

The nature of said invention consists in the use of the ashes ofcotton-seed or other oilyielding vegetable substance when mixed withother earthymatters by means of oil orrosin to make a cement having thecapability of being molded into almost any shape and assuming theappearance, hardness, and, formost purposes,thedurabilityof stoneiuat'ew hours.

To enable others to manufacture and use thisdnvention, I will proceed todescribe its composition and construction.

My chief composition is composed of resin (or rosin) and cotton-seedashes (or other vegetable ashes) and sand; but it is necessary todescribe first the furnace and implements used by the inventor himself,and then proceed to the construction of theartificial stone, that theprocess may be the better understood. He had a low furnace built ofbrick and mortar, with two large iron kettles set in it (but one kettleis all sufficient) some six or eight inches from the ground, with a fluepassing under them and pipes to carry off the smoke. Under the front endhe kindled afire. Heplaced on the ground planks nailed together like abatten-door, upon which he placed a sheet of Russia iron, and upon thata frame or mold about two and onefourth feet wide and four feet long andtwo inches deep. Take care to have the timbers ofthe mold strong enoughnot to admit of their springing out when the composition is pressed intoit, and the mold for a large flagstone is now ready. The striker is abar of iron about three-eighths ot'an inch thick, with an eye on thecenter of one side to receive a handle, and long enough to reach acrossthe mold. A plasterers and abrick-laycrs trowel and a stick to stir withcompletes the apparatus. Now throw thirty pounds (or about thatquantity) ofresin into the kettle, and when melted throw into it a halfpint (or a pint, if preferred) of cottonseed ashes and the same quantityof charcoaldust or bituminous-coal dust, or a little lamp'- blank orSpanish brown as coloring-matter, and then stir in dry sand until themixture will fall short from the stick, when it is ready for the mold.Every iron tool that touches it must be heated. Ladle itoutwith a commonshovel,

supplied by wood or other vegetable ashcs,'as

these have been thoroughly tried without any good result. The productbecomes brittle and unlit for durable service, while a cement made fromcotton-seed ashes is permanent.

What is claimed as J OIIN R. RnMING'roNs invention is The use ofcotton-seed ashes or the ashes of any other oil-yielding vegetablesubstance, as

an ingredient of a cement, substantially as herein set forth, whetheritbe mixed with rosin and earthy matters or with oil and earthy mat-.
